Guys:
I have finished the new beach sand batteries, and they are showing the expected results of much higher mA readings. But there is a catch... they are working just like a capacitor. When first connected to the meter each battery will bounce the meter's needle up to about 40 mA. Then drop fairly quickly (one minute) as I am watching, down to about 3 mA, and stay there. The voltage is almost 2 volts at first, but also drops to about 1.2 volts, or so after a while. In any case they are stronger than the previously made ones, but still drop down to a lower light level after a while.
I have not been able to light a Joule Thief with them yet, even when three of them in series are showing 6 volts readings. I have not had a chance to connected them both in series as well as in parallel, at the same time yet, Or to connect the right Jt to them, with no resistor in the circuit, like I did with my solar Jtc.
I think that making a copper coil that goes inside of the can that looks like one coil of the Basher cone antenna, may work better than a straight coil. Same principal perhaps. I have one coil ready made for that test next.
I think that these are capacitor-batteries, but like a lower farad capacitor they don't hold their original standing charge for long, but do bounce back quickly. I know they would charge the right capacitor bank or a battery if given enough time, as I've already tried to charge a capacitor, with success. The one with weakest voltage and current will restrict the flow of juice to the rest of them in series, just like a restriction in a water hose.
Great fun, so far...
